The answer is -1296/7. Or in short form -185 1/7
The the parabola opens upward it has a minimum and if it opens downward then it has a maximum :)
360in^3
The equation of the cone is just the cylinder equation divided by 3, so I order to get the volume of the cylinder you do the opposite: multiply by 3!
So 120 x 3 = 360 :)
1/2, 3/8, 1/7 hopefully I am right I’m not sure
Sort the numbers in ascending or descending order, then eliminate the greatest and least numbers until you're left with the middle two. The median is the average of the last two numbers.
For example, the median for the set

is 3 because the middle two numbers are 2 and 4, and their average is
